The functional forces depending on the bite, tongue and cheek, and the artificial forces caused by the prosthetic or orthodontic mechanism are absorbed by the periodontal ligament. The dental root surface area is closely related to support of the periodontal ligament. The same applies to the shape of the root, the attachment direction and the implanted condition. Few reports, however, have been made on the subject of the measurements of the root surface area. We devised a new method to measure the root surface area using computer analysis of the moire, and gained the following conclusions ; 1) The dental root surface area along with the computer analysis of the moire was determined without damaging the teeth. 2) The sectional interval was reduced by the moire and the precision was increased. 3) The method using the moire and computer is superior in working capacity compared with past methods.
